Compatible with car:
This excellent downpipe from Prosport features a fully polished finish, a bell-mouth collector, and an extra bung for your wideband air/fuel gauge. (There's an included plug if you don't have one of those.)
Construction is all stainless steel, from the 1/2" flanges to the fully polished 3" mandrel-bent tubing. A 3" gasket and a pair of nuts and bolts are included for the back of the downpipe; we would suggest also replacing the downpipe-to-turbo gasket, which you can find here or here.
NOTE: Whenever you modify a factory catalytic converter, you may end up with a "catalytic converter efficiency" check engine light (CEL) code. Please read our FAQ page on catalytic converters before purchasing this part.
This downpipe will bolt up to most any cat-back that's designed to bolt up to a flat flange. It is are NOT ideal for the stock cat-back (which uses a smaller donut gasket connection) but could be made to fit with an adapter.
A rear gasket, nuts and bolts are included. The turbo-to-downpipe gasket is not included.
Fits all 2008-2014 WRX and 2008+ WRX STI, including 2015+. Also fits manual-transmission Legacy GT and Outback XT, model years 2005-2009.
